SPECIFICATION forming part of Letters Patent No. 386,146, dated July1'7, 1888.

To aZZ whom it may concern:

Be it known that I, JAMES G. MALLERY, a citizen of the United States,residing at Flint, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements incultivators.

The invention consists in the peculiar construction and arrangement ofthe various parts, whereby all requisite adjustment of the parts isprovided for,and in the combinations of the parts, all as more fullyhereinafter de scribed.

Figure 1 is a perspective view of my improved cultivator. Fig. 2 is avertical crosssection showing the pivotal connection between the bars.Fig. 3 is a vertical crosssection through the head of one of the rearcultivator-standards.

In the accompanying drawings, which form a part of this specification, Arepresents the central and draft bar of the cultivator, the forward endof which is turned upwardly, as shown, and carries the hook B, or othersuitable device, to which the draft may be applied.

C are the side bars of the frame, their forward ends being twisted orbent at right a11- gles, as shown, and have suitable holes formedtherein to receive the lugs a, which project inwardly from the ends ofthe headplates D, the latter being secured to the central ban-A, bybolts I). The rear ends of these side bars, 0, have pivotally secured tothem the lateral spreader-bars, D, the overlapping ends of which passthrough a link, E, which embraces the central bar, A, and is providedwith a setscrew, F, by means of which the two bars D may be firmlyclamped upon the central bar, and thus retain the side bars at theiradjusted angle from the line of the central bar, as the nature of thework to r be performed may require.

G are the standards, which carry the cultivator-teeth H. The upper endsof these standards are provided upon their inner faces with a circularhead, I, the flat face of which is radially corrugated to engage with asimilarly-formed face upon the wedgeshaped disk J, the rear face ofwhich is provided with a channel or groove to partially embrace the barsof the frame, the standard and disk being secured to the bar by means ofa bolt, K. By this construction it will readily be seen that thecultivator-teeth may be easily adjusted, so as to be parallel with theline of draft, and so as to give a greater or less pitch to the teeth.

At the rear end of one or both of the side bars the standard G of thescraper H is secured at its upper end in a head, I, which is providedwith a corrugated face to engage with a corrugated disk, J, such headand disk being secured to the bar by means of a threaded bolt, 0, whichis cast with the head I, and which passes through a central hole in thedisk and a coincident hole in the bar, receiving a nut, cl, upon itsinwardly-projecting end. The standard G passes through a vertical holein the head I, and is secured therein by means of the set-screw h.

L represents the handles, the lower ends of which are secured to the barA by the bolt 6.

M are standards, preferably made in two parts, the lower ends partiallyembracing the bar A, and are secured thereto by a bolt, i, their upperends being provided with slot-s j.

7; are bolts which pass through the slots j and the adjacent handles forthe purpose of se curing the parts in their desired relative positions,such adjustment of the handles being limited by the length of the slots,which may be more or less.

N is the cultivator-wheel,which is journaled between the lower ends ofthe hangers O, the upper ends of which are provided with heads P, theinner faces of these heads being corrugated to engage with thecorrugated faces of the disks R, the whole being secured to the bar A bya suitable bolt, S.

By this construction and arrangement of the parts it will readily beseen that all necessary adjustment is provided for, so as to meet therequirements ofthe work to be performed, while at the same time Iproduce a simple and compact implement.
